and capacitors generate a high impedance to bass frequencies -- it’s like pouring water on the side of a hill: the water will never travel uphill against gravity!

WOOFER MODULE BINDING POSTS:

The WBT Platinum Signature binding posts supplied on the VR-5 Anniversary are the finest quality available and can accept raw wire, spade lugs, pins, and banana plugs. Use a contact enhancing fluid once a month on all RCA plugs and binding posts for best results. Contact cleaner/treatments increase the sweetness, air, soundstage depth, and smoothness to an amazing degree, try it!

RECOMMENDED CABLES BY VON SCHWEIKERT AUDIO

Since most wire companies do not have engineering experience with our bi-wire design, we have spent four years designing the best possible speaker cables for our customers. Please see our Website for information on the cables we have designed expressly for use with our line of speakers. Our cables have been designed for bi-wiring our speakers in particular and the tonal characteristics of our wire are a perfect match for our speakers. Although there are several good brands of wires on the market, only our specialized cables have been designed with our speakers as the partner.

BI-AMPING THE VR-5 Anniversary Model

If the tightest bass is desired, use a solid state amplifier on the woofer modules. If you value “image float” and “liquid”-sounding midrange/treble response, use a tube amplifier on the M/T’s. You will not need an outboard electronic crossover, since the crossovers in the speakers will still continue to work. Although it is true that louder treble output can be obtained by high-pass filtering the tube amp, the loss of transparency is usually not worth it. The clean volume obtainable without a high-pass crossover will be usually satisfying for anyone but a metal head. You will need a preamp that has twin outputs, but if you have only one set, use high quality Y-jacks available from your high-end dealer.

Balancing of the volume levels when using amps with different input sensitivities can be accomplished by outboard level controls available from your dealer at very modest cost. If the amplifiers have input sensitivities which are fairly close, even if they are different brands, there will be no need for level controls.

VON SCHWEIKERT TUBE AMPLIFIER FOR MIDRANGE/TREBLE

We have been seeking a tube amplifier for use with our higher sensitivity models, and at last, we have discovered a new company that has built the perfect amplifier with our specifications for use with the VR-5 Anniversary Model speaker system. Our new amplifier uses push-pull 300B tubes for the highest degree of musicality and transparency, and we believe it is the most transparent and musical amplifier from 100Hz upwards to 50kHz. This amplifier has a built-in volume control so you can balance the midrange and treble volume level to any solid state amplifier you wish to use for the woofer cabinet. Please see our website or call us for further information on this new amplifier.

VERTICAL BI-AMPING: If two stereo amplifiers of the same brand and model are available, try using this method of wiring. One channel will drive the woofer module, while the other channel of the same amplifier will drive the upper M/T’s.

VR-5 specifications

The Von Schweikert Audio VR-5 stands as a true testament to high-fidelity audio engineering, attracting audiophiles with its impeccable sound reproduction and innovative design. This loudspeaker is part of Von Schweikert's acclaimed VR series, consistently lauded for its advanced technology and precision craftsmanship, which together create an immersive listening experience.

At the core of the VR-5's design is its unique three-way, four-driver configuration. This setup includes a large woofer, a midrange driver, and dual tweeters, each meticulously engineered to deliver a specific frequency range. The woofer is designed to produce powerful bass, capable of extending well into the lower frequencies, while the midrange driver excels in rendering vocal clarity and scale. The dual tweeters ensure that high frequencies are crisp and detailed, providing a sense of airiness and openness to the overall soundstage.

One standout feature of the VR-5 is its proprietary V-Frame design, which minimizes resonances that can color sound. This design innovation, combined with high-quality materials, lends the speakers superior structural integrity, ultimately resulting in more accurate audio playback. The use of advanced cabinet construction techniques, including extensive internal bracing, ensures that unwanted vibrations are kept at bay, allowing listeners to experience music as it was intended.

Additionally, the VR-5 incorporates advanced crossover networks that contribute to seamless integration between drivers. These crossovers employ state-of-the-art components designed to preserve signal purity and maintain phase coherence, further enhancing the fidelity of sound reproduction. The result is a coherent sonic image where instruments and vocals occupy defined positions, enriching the spatial characteristics of any recording.

Another key characteristic of the VR-5 is its ability to adapt to different room acoustics. Featuring adjustable rear bass ports and a customizable crossover frequency, users can fine-tune the speaker’s performance to suit their specific environment. This flexibility ensures that audio enthusiasts can enjoy an optimal listening experience, regardless of their space.

In summary, the Von Schweikert Audio VR-5 is a highly regarded loudspeaker that brings together state-of-the-art engineering, innovative design, and sophisticated technologies. With its three-way driver configuration, robust construction, advanced crossover networks, and room adaptation capabilities, the VR-5 offers an exceptional listening experience for even the most discerning audiophiles.
